Washer displays HE1; overheating detected in heater circuit.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Heater relay on PCB stuck on, Thermistor reading incorrectly, Heater not submerged due to low water level, Scale buildup causing hot spots

Safety: Unplug the washer immediately to prevent damage.

Check water level: Ensure the washer is filling properly (no 4C/4E errors). Low water can expose the heater.
Inspect thermistor: Test the temperature sensor for correct resistance at room temperature and replace if faulty.
Control board: If heater is energizing when it should not, the main PCB heater relay may be stuck and the board will likely need replacement by a professional.
